Title: Improvements in or relating to programming of machine tools
Inventor: SELBY JAMES
IPC: G05B19/04
Filed: 1965-04-12
Abstract: 1,090,654. Machine tool details. B. ELLIOTT (MACHINERY) Ltd. July 12, 1966 [April 12, 1965], No. 15440/65. Heading B3B. [Also in Division G3] A control arrangement for a milling machine having a work-table movable along two or three mutually perpendicular axes by an electric motor selectively coupled to the work-table by electromagnetic clutches, comprises a plurality of control circuits for energizing the clutches which are sequentially activated through a variable connecting device by a plurality of limit switches for terminating table movements at predetermined points along the axes. As shown, clutches for longitudinal, crosswise and vertical movement are controlled by solenoids L, C, V, respectively, each of which has a similar control circuit. The control circuits additionally control solenoids CL, CCL, for clockwise and counterclockwise rotation of a drive motor, and a solenoid Q energizing a quick traverse clutch. In the circuit shown in detail for solenoid L when current is fed to a point X the solenoid CL is energized and associated contacts CL3, CL4 complete a holding circuit and energize the solenoid L for table lift movement. Energization of solenoid L opens contacts L1, L2 preventing operation of the control circuits for solenoids C and V. At the end of the movement a trip dog, not shown, actuates a limit switch LL whose upper contacts snap-over to de-energize solenoid CL and connect the supply to a terminal Y. A table movement to the right is initiated by a feeding current to a terminal X associated with a limit switch LR energizing the solenoid CCL. When a quick traverse is required the current is applied to a Z terminal which is connected through the lower contacts of a limit switch to a solenoid Q. The lower contacts are only actuated by special long-reach dogs. The interconnection of the X, Y and Z terminals is effected through a plugboard, Figs. 2 and 3, not shown. It is stated that alternatively the interconnection can be effected by shaped keys, punched non-conducting plates or printed circuits.

Title: Rotors for multi-stage axial flow compressors or turbines
Inventor: FRENCH MICHAEL JOSEPH
IPC: F01D5/06
Filed: 1957-05-15
Abstract: 836,920. Turbine and compressor rotors. NAPIER & SON Ltd., D. May 15, 1958 [May 15, 1957], No. 15470/57. Class 110 (3). A rotor for a multi-stage axial-flow compressor or turbine comprises several sections having hollow cylindrical or frusto-conical portions with flat faces at the extreme ends thereof which lie in parallel planes perpendicular to the axis of rotation and which abut against the adjacent end faces of the adjacent sections, dowels being provided which extend radially across the abutting end faces and fit tightly in recesses in adjacent sections. The compressor rotor shown comprises a series of abutting cylindrical sections 14 each having an annular flange at the periphery of which rotor blades 11 are mounted. The rotor also comprises two end sections 16, 17, which abut against the end sections 14 and have cylindrical portions 20, 21 respectively which carry the inner races of support bearings. The cylindrical sections abut in planes lying normal to the axis of rotation and radially-extending semicylindrical recesses are formed in the edges of the sections, the recesses in adjoining sections co-operating to form cylindrical openings in which cylindrical dowels 25 are engaged. The dowels have heads 26 to prevent radial outward movement, the heads being formed with diametrical grooves 27 in which circlips 28 are engaged so as to prevent radial inward movement of the dowels. A tube member 23 extends through the centre of the rotor assembly being tightened by a nut 29 so as to draw the end sections 16, 17 towards one another, thereby holding the cylindrical sections 14 in axial compression. The semi-cylindrical recesses are formed by assembling the cylindrical sections together and then drilling radial holes, the diameter of the holes being slightly less than that of the dowels. The tube 23 is inserted hot so that in cooling, the dowels and adjacent parts of the sections are somewhat distorted so as to ensure a tight fit of the dowels in the recesses. Sealing rings 32 may be provided between the platforms 33 of adjacent rows of rotor blades.

Filed: 1916-10-30
Abstract: 109,041. Soc. Auxiliare de Brevets. Aug. 19, 1916, [Convention date]. Tubes or containers, collapsible.-A hypodermic syringe, of the type provided with a stiletto passing into the needle and carried by a protecting- cap, is so constructed that the stiletto does not normally project into the liquid-container but is separated therefrom by a metal diaphragm adapted to be perforated immediately preceding use, by forcing forward the stiletto before withdrawing it. In the form shown in Fig. 1, a neck 2' on the collapsible metal container 1 is engaged by a sleeve 8, to which a glass sheath 9 carrying a stiletto 10 is cemented. The neck has grooves 7 engaging ribs on the sleeve 8, and accidental movement is prevented by projections 11 formed by pressure. The sheath and stiletto may be pushed downwards so that the stiletto punctures a metal-foil disk 6 carried in a recess surrounding the outlet bore 3 of the syringe. Fig. 3 shows a modification in which the metal disk 12 covers the whole of the end of the tube 1, and in which the sheath engages the container by screwthreads. In a further modification separate metal disks are omitted, the outlet bore 3 being carried only so far into the neck of the syringe as to leave a blind-end sufficiently thin to be easily perforated by the stiletto. In all the modifications, the needle is fixed in the outlet bore by pressure.

Title: Improvements relating to electromagnetic relays
Inventor: ROBINSON SYDNEY
IPC: H01H51/08
Filed: 1954-05-26
Abstract: 815,642. Electromagnetic relays. JACKSON, S. W. Aug. 25, 1955 [May 26, 1954], No. 15593/54. Class 38 (5). A relay having spring blade contacts 3a opened and closed by successive operating current impulses comprises an L-shaped armature 2 in two parts 3, 4 hinged together at 5, the part 4 being biased away from the core by a spring 6 anchored at one end to the frame 1, and the part 3 actuating the contacts. An arm 7 freely suspended from the armature has a bent-out end 8 co-operating with notches 19, 22 formed in plates 9, 10 arranged side-by-side and pivoted at 12, 13, respectively on a bracket 11 fixed to the frame 1. A spring 14 is stretched between lugs 15, 16 on the plates so that in the relay position shown a pin 17 on the plate 10 is held in a slot 18 in the member 9, and a part 24 on the plate 10 prevents movement of the armature part 3 towards the frame 1, whereby the contacts are held actuated. On reception of an impulse the armature part 4 moves down and the end 8 enters the notch 19 to tilt the plate 9 counter-clockwise whereby spring 14 moves plate 10 clockwise and pin 17 moves into slot 20. The part 24 thus moves away from part 3 so that the contacts 3a are free to move to their non-actuated position. As the end 8 moves up on termination of the impulse it engages the notch edge 21 and is thereby moved to the right so that on the next impulse it moves into notch 22 resetting the pin 17 in the slot 18 and the part 3 actuates the contacts. On termination of the impulse the part 3 is held by the part 24 and the end 8 engages the notch edge 23 and is moved to the left in readiness for the next impulse. In a modification (not shown) the hinge 5 is omitted and the contacts are operated directly by the plate 10.

Title: Improvements in or relating to the production of a cinematographic film record from a recording of television video signals
Inventor: BERKELEY PHILIP ROLAND
IPC: H04N5/84
Filed: 1963-04-22
Abstract: 1,096,811. Television. IRIS PRODUCTIONS Ltd. July 15, 1964 [April 22, 1963], No. 15792/63. Heading H4F. [Also in Division G5] In an arrangement for making a cinematographic film record from an existing magnetic tape recording of television video signals, two video signals are derived simultaneously from the magnetic tape by means of a tape reading head having two head wheels 11 and 20, Fig. 1, separated by a distance corresponding to onefield length period, and simultaneous visual displays which are produced from each of the signals are projected on to the cinematographic film to form a single exposure image with respective scan lines of the two displays interlaced, the film pull-down being effected during alternate field periods. The disc-form head wheels 11 and 20 each have four equispaced inset transducers 12 and 21 around their peripheries and the video tape record 18 is held at the requisite small clearance distance from the head wheels by means of 90-degree arcuate suction heads 17 and 23. The head structure thus provides two video signals simultaneously which represent respectively the even-numbered line raster of one field and the odd-numbered line raster of the immediately adjacent field either before or after such even-numbered line field. An interlaced visual display of the two simultaneous output signals e.g. representing fields N and N + 1, may be produced on the screen of a two-gun form of double-beam cathode ray tube during alternate field periods and projected on to a frame area of a cine film, Fig. 4 (not shown). In a further embodiment, Fig. 5 (not shown), a single-beam-type cathode ray tube is employed, an electronic switch operating to supply the two signals N and N+ 1 alternately to control the beam intensity whilst the beam itself is displaced in the vertical or field scan direction by additional deflection means resembling a " spot wobble " arrangement. In a further embodiment, Fig. 6 (not shown), the simultaneously occurring video signals N and N +1 are applied respectively to control the beam intensities of two separate cathode ray display tubes and the separate images are multiplexed by means of a halfsilvered mirror to present a single composite image for projection on to the cine film. The video signals may be derived from the magnetic tape at a speed slower than that at which they were originally recorded.

Title: Speed indicating arrangement for moving bodies, principally aerial moving bodies
IPC: G01P3/66
Filed: 1931-05-30
Abstract: 380,084. Magnetic tests and measurements. MICHAUD, F., 28, Rue Monge, Paris. May 30, 1931, No. 15870. Convention date, May 31, 1930. [Class 37.] A speedometer, particularly for use on aeroplanes, utilizes the E.M.F. produced in a conductor moving in the earth's magnetic field to obtain the speed and direction of movement. In the arrangement, shown in Fig. 1, the conductor 1 is connected to the cathode filament 2 and to the control grid 3 of the electronic discharge relay 4 with anode plate 5 and a second grid 6 raised to a constant positive potential by a battery 9 to facilitate the electronic omission. The variations in the potential between the ends of the conductor 1, caused by it cutting the earth's magnetic field, produce variations in the filament-plate current which variations operate directly or through the intermediary of an appropriate amplifier connected to the terminals 10, 11 a suitable measuring apparatus. To facilitate amplification and avoid errors due to variations in the apparatus, it is mounted for continuous rotation about a vertical axis Z1, Z2 passing through the cathode filament 2 of the relay 4, and connection is made by brushes and rings on this axis. To determine the direction of travel a pair of conducting contacts 18, 19, Fig. 3, is employed in the ring in the circuit of the control grid 3. In another modification a pair of relays rotated in opposite directions may be mounted, as shown in Fig. 4, on a turntable which can be turned to obtain maximum and minimum readings of the E.M.F. thus giving the direction of travel and affording a quantity from which the speed can be calculated.

Filed: 1967-04-06
Abstract: 1,162,908. Rectifying; control of D.C. motors. SKODA, OBOROVY PODNIK. 6 April, 1967 [7 May, 1966], No. 15874/67. Headings H2F and H2J. In a multi-phase anti-parallel rectifier system for supplying a D.C. motor 8 from an A.C. source 3 via a positive rectifying branch 1 or a negative branch 2 according to the desired direction of rotation of the motor, control signals are derived from the control junctions of the thyristors in one branch which are conducting and are used to prevent the application of ignition pulses to the thyristors in the other branch, thereby preventing both branches from conducting simultaneously. The control junctions of thyristors 101-103 in branch 1 are connected to a sensor unit 15 which detects if any of the thyristors are conducting, and if they are, inhibits a gate 14 thereby preventing control signals from a regulator 12 from passing through the control unit 11 to the thyristors 201-203 in branch 2. Similarly, if one of the thyristors 201-203 conducts the gate 13 is inhibited and control signals cannot pass to the thyristors in branch 1.

Abstract: 439,119. Thermally-actuated valves. TERRELL, T., and ALADDIN INDUSTRIES, Ltd., Aladdin Building, Greenford, Middlesex. May 29, 1934, No. 16019. [Class 135] [See also Group XI] In a vapour burning lamp or stove a phial 13 containing distilled water or other fluid and communicating with a bellows 2 is provided within the vaporizing tube 6, the vaporization of the water when the tube 6 is heated sufficiently to vaporize the fuel contained therein causing a bellows 2 to expand and to depress a plate 15, thereby admitting fuel from the pressure reservoir 1 to a tube 4 leading to the tube 6 and withdrawing a valve 8 carrying a pricker needle 9 from the vapour nipple 7. The tube 6 is heated at starting either by an annular trough burner or by a torch 25 which may be supplied with air from the reservoir 1 through a pipe 24. The inlet 23 to the pipe 24 is controlled by a valve 22 which is connected by a pivoted arm 20 and a rod 19 to the plate 15. The valve 22 is moved to the closed position when the vaporizing tube 6 is heated sufficiently to expand the bellows and operate the plate 15. The tube 6 is then maintained at the fuel vaporizing temperature by the flame from the main burner 10 which may be fitted with an incandescent mantle. The plate 15 is attached to a plate 3 carrying the bellows by springs opposing the expansion of the bellows and may be guided by a rod or rods 17 fitted with springs 30. Instead of the bellows 2 a chamber fitted with expansible diaphragms may be used.
